Free sex in Copenhagen

Prostitutes will offer free sex to delegates at the  UN climate summit in Copenhagen next week. It is not, as I first thought, an inititative of Denmark which cares so much about the success of the event that it wants to please the delegates as much as possible. No, it is not that prostitutes themselves care that much about climate change...Rather, they are protesting against the city hall distribution of postcards in Copenhagen's hotels that say "Be sustainable: Don't buy sex." The prostitutes will accept these postcards for payment. In your face city hall! Why such a move form city hall, when the service could have greased the wheels of negotiations, offering some pressure relief? I wonder what the penguins think.
